Summary
In the Linux kernel, the following vulnerability has been resolved:
erofs: fix wrong kunmap when using LZMA on HIGHMEM platforms
As the call trace shown, the root cause is kunmap incorrect pages:
BUG: kernel NULL pointer dereference, address: 00000000
CPU: 1 PID: 40 Comm: kworker/u5:0 Not tainted 6.2.0-rc5 #4
Workqueue: erofs_worker z_erofs_decompressqueue_work
EIP: z_erofs_lzma_decompress+0x34b/0x8ac
z_erofs_decompress+0x12/0x14
z_erofs_decompress_queue+0x7e7/0xb1c
z_erofs_decompressqueue_work+0x32/0x60
process_one_work+0x24b/0x4d8
? process_one_work+0x1a4/0x4d8
worker_thread+0x14c/0x3fc
kthread+0xe6/0x10c
? rescuer_thread+0x358/0x358
? kthread_complete_and_exit+0x18/0x18
ret_from_fork+0x1c/0x28
---[ end trace 0000000000000000 ]---
The bug is trivial and should be fixed now. It has no impact on
!HIGHMEM platforms.
